In the fluid conveying links of industries such as food,chemical engineering and pharmacy,the conveying of materials with high viscosity and high hygiene requirements has always been a core difficulty in working conditions.With its own structural advantages,the cam rotor pump is increasingly widely used in such scenarios.However,many front-line operators and purchasers still have cognitive blind spots in the performance details and key operation and maintenance points of the equipment.Below are several core practical knowledge points sorted out for you.

-Bonve Pumps Cam Type Double Rotor Pump-

Many people tend to confuse cam rotor pumps with gear pumps.Although both belong to the category of positive displacement pumps,there are obvious differences in their structural logic and applicable scenarios.Driven by synchronous gears,the cam rotor pump drives dual rotors to rotate synchronously in reverse directions,and a stable vacuum environment will be formed at the inlet side of the pump chamber along with the rotation of the rotors,so as to complete the suction and discharge of the medium.The equipment as a whole features wear resistance and corrosion resistance,and its flow-through structure is easy to clean,which is suitable for production scenarios with high hygiene level requirements and high material viscosity,and is widely used in the fields of food processing,fine chemical engineering and pharmaceutical production.The structural design of the rotor pump also allows the maintenance of core components without disassembling the pump body and pipelines,greatly reducing operation and maintenance costs and downtime.Gear pumps realize medium conveying through the meshing and separation of a single pair of meshing gears,and the medium is squeezed out by the gears along the inner wall of the pump body.The core characteristics of this type of equipment are small flow rate and high head,making it a common conveying equipment for high-viscosity liquids and semi-solid materials such as saponin,silicone oil,rosin and heavy oil.

Regarding the operation before equipment startup,many people wonder whether priming is required.Priming must be completed before the cam rotor pump is started.Since the flow-through components of the equipment are of all-metal structure,dry running without medium is strictly prohibited,otherwise it will cause rapid wear on the contact surfaces between the rotors and the pump chamber.The self-priming performance of this type of equipment is very stable,with a rated suction lift of up to 9 meters,which has outstanding adaptation advantages in scenarios such as mobile pump truck matching and integrated tanker unloading and tank sweeping.

After the equipment has been running for a period of time,if the suction capacity declines,you can check and solve the problem according to the corresponding steps.First,check the wear degree of the rotor components.If the rotor clearance exceeds the allowable range due to wear,replacing brand-new rotors in time is the core way to restore the suction capacity.If the rotors are in good condition and the clearance is normal,you can appropriately increase the operating speed of the equipment to compensate for the suction capacity.You can also reserve a margin in advance during the selection stage,choose a pump model with a larger flow specification to run at a lower speed,and then maintain the working condition requirements by increasing the speed after the rotors have natural wear in the later stage.In addition,the matching degree of rotor materials will directly affect the suction effect and service life.For example,when conveying food-grade media,food-grade materials such as 304 stainless steel should be selected to take into account both working condition stability and hygiene compliance requirements.

According to different on-site installation conditions and working condition requirements,cam rotor pumps support multi-dimensional customized adaptation.The drive structure form can be adjusted according to actual needs,including details such as the installation orientation of the motor,the orientation,spacing and material of the inlet and outlet flanges.Adopting a top-mounted motor installation layout can effectively reduce the overall floor space of the equipment,which is especially suitable for the overall skid-mounted system design requirements,facilitating on-site integration and rapid installation.
